To identify variables affecting outcome in patients with benign paroxysmal positional vertigo (BPPV) treated with canalith repositioning maneuvers. ⋯ Patients with benign paroxysmal positional vertigo not located in a single posterior semicircular canal are more likely to require multiple visits for canalith repositioning.

Randomized Controlled Trial Clinical Trial
Intravenous Lorazepam versus dimenhydrinate for treatment of vertigo in the emergency department: a randomized clinical trial.
To determine whether lorazepam is more effective than dimenhydrinate in relieving the symptom of vertigo in the emergency department setting. ⋯ Our results suggest that dimenhydrinate was more effective in relieving vertigo and less sedating than lorazepam at the intravenous doses administered in this study. Dimenhydrinate appears to be the preferred medicine for patients who present to the ED with vertigo likely to be of peripheral origin.

To correlate patient response and recurrence rate after canalith repositioning to clinical presentation and cause of BPPV. ⋯ Canalith repositioning was effective in 99% of patients based on elimination of nystagmus. Partial responders probably experienced resolution naturally over time because of a difference in pathophysiology. Higher recurrence rates can be expected when the cause is thought to involve an ongoing process.

Postural stability using different neck positions in normal subjects and patients with neck trauma.
Subjects with neck problems, such as whiplash injuries, often complain of disturbed equilibrium and, in some instances, provocation of the neck position can elicit such problems. The importance of neck proprioceptors for maintaining balance is gaining increased interest, moreover the function or malfunction of the otoliths may disturb equilibrium in certain head positions. The aim of the study was to create a reference material for postural control and its dependence on head position in healthy subjects and to compare this with a set of patients with known neck problems and associated vertiginous problems. ⋯ The patient group differed statistically from all groups of normal subjects. This suggests that neck problems impair postural control, and that the head extended position is a more challenging task for the postural system to adapt to. Whether this is due to utricular malpositioning, central integrative functions or cervical proprioceptive afferents is not within the scope of this study to answer.

Dizziness is a common symptom that, despite extensive medical evaluation, often remains unexplained. Psychiatric or psychosomatic disorders underlie the condition in 30-55% of the cases. ⋯ The assessment of psychiatric and psychosomatic symptoms should always be included in the neuro-otological examination of dizziness. Early interdisciplinary treatment should be initiated with the aim of preventing chronification of psycho-genetic vertigo.
